-8 + 12e = -20
12e = -20 + 8 (Make both sides equal; to remove the -8 on the left we need to add 8, which adds 8 to the right-hand-side)
12e = -12 (Now divide by 12 to get e)
e = -12/12
e= -1
A = 77 + 5 + 8 = 20
20 = 400
20
8
To solve the equation 8 plus what equals 20, we need to find the missing addend. We can do this by subtracting 8 from 20, which equals 12. Therefore, 8 plus 12 equals 20.
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
-8 + 19 = 11
y equals negative 8.
20
Addition is commutative. That is, a + b = b + a for all a, b
6-4-8-2=20 is the answer
x=3
